r screw 9 a combined trnnsinitter'srnd receiver To all whom it may concern.-

Be it known thrrt l, Jorrx .Hnrscn, Jr., a citizen of the United States of America, resioing at Allegheny, in the county of Allegheny and Strte of Pennsylvrrnia, have invented certain new and uscrul lnLpLoven'Lcnts in Receiver-Supports, of which tire following is a specification, reference bring hard therein to the accontpzrnving drawings.

This invention l'tlrtttS to recr iver-supports;

and the objectof the invention is to oispcnsc with the ordinary type 01 rr'cr iver conunonly used and provide a. combined trrznsu itter and receiver that will always be in position ready for use.

Another object of this invention is to pro vide a receiver that can be reversed, \vhereb it can be either used for the lclt em or the r1gl;t ear.

With these and other objects in view, Which Will nrore rendrly spperrr rs t :ernvrn tron is better understood, the son cccrlsrsts in the novel construction, crnnlzin ticn, and arrangement of p11 ts to be herrinetter n:.oie fully described, and then spe out in the appended ClttlII'S.

Referring to the drawings, t'orrring port of this specification, like numerals of relerrnce designate corresponding pm ts throughout the several views, in wl1icl1 Figure 1 is 2r plan of n .y improved receiversupport, illustrnting the some in it reverse position in dotted lines. l ig. 2 is a crosssectionsl view taken on the line at a: 01' Fig. 1. Fig. 3 is it horizontrl scction;:l view of o porticn of a receiver-arm, illustrating one ol the electrics] connections made thereby. l ig. l is a sin-.ilsr view, illustrating enctlrcr electrical connection. Fig. 5 is rr front elevation of my in proved rccciver-support. ig. 6 is a side elevation ol' :1 portion of the recriversupport. Fig. 7 is :r verticcd StCtlOllcLl view 01 the crisrng continuing the contact-arms ol the receiver-suppor t.

To put my invention into PHMUCO, 1 provide a well-board 1 ol rr telephone with n plate 2, srrid plnte bring secured to the board 1 by screws 3 or siniilti' fastening means. Upon te plnte 2 is mounted it nlovnble plate 4, stid pl..to bring I rovirled with a son .icirculzrr slot 5, through WillUll extends a screw 6, can ied by the plate 2. The movable plate 4 is held and locked in engagement \\it.r the plrrte 2 by n thumb-screw 7. Extending out- Wft1'tl \"l l()1l1 the movable plate 4 i an arm 8, to which in srdjus tzrbly connected bv 0. thumbcilicnlly pointed frame 10. The frame upon its one end is provided with a. conventional form of transmitter 11, while the oppcsite end of the l'rzrme is provided with :1 pr\ oted arm 12, carrying at pivoted 1t(cl\0l-l.t:id 14, the inter ior 1110i].- urrlslu tlzcreol', incluuing tle diaphragm, being sirrilurlo 2.11 orrrinnry rcctiver. Tlis is also true in lrlntlcn to tre interior mechanism ol the trzxnsn ittcr 11.

The frame it) is provided with a curved extension 15. and :nrrrched r0 srrid extension and rhe receiver-arm 12 is :1 spring 16, normrrlly holding the receiver-arm in the position illusrrrrred in full lines 01 Fig. 1 of the drawings. '.lhe extension 15 carries a. casing 17, lnrving openings 18, rhrouglr which the receiver-arm .l. (.XrCIlLlS. 1n the crrsing 17 zrrc mourned two contact-blocks 1t), lurving terminals 21) to receive rhe positive rrnd negative wires 21 of :r telephone-circuil, these wires being at predetermined times in corrmunicrrtiorr with the rrrrnsmirrer 11 and re cciver 14. '1'his is accomplished through the medium ol an insuloed contactingbridge 22, carried by the arm 1'2 within the crrsing 17, the circuit passing through the blocks 12), bridge 22, wires 22 to the transmirter 11 and through wires 123 to the recciver-herrd 14.

in the cirsing l7 benezrlh the blocks 1!) are mounted two nngulrrr contact-arms 23, with which connect wires 21-, adopted to complete it circuit which devermines when the rclephone is in use. This is :rceomplislunl by providing the arm 12 wirh on insulated conrzrct-sdrrup 25 carried by the arm 1'2 within the crrsing 17. The sr irrup 25 is :tlltLPlOLl to cont act with the rrrms 23 when the bridge 22 is out of corn tzrct wir lr the blocks 19, and in this manner complrxe :r. circuit for rrrnilying tlre'operrrror ol :r cenrrrrl tclephone-sirrtion that the telephone is out of use.

in operruion. :r person desiring to transmit it message over the telephone plnecs his or her left our :rgoinsl'. tlze receiver 14, pressing the some outwardly until it is in the position illustrzrlcd in dotted lines in Fig. 1. When in this posirion a circuit is completed through the. receiver-head 14, wires 23", bridge 32, blocks 19, terminals 20, rrnd wires 21, also wires 23 and transmitter 11. To mnintrrin the receiver-heard 14 in such a position that it will not break the circuit for tronsrnitting or receiving a message, I have provided the extension 15 with a. pivoted arm 26,- said arm having a rightangular ex- I tension 27, adapted to engage in a socket 28, carried'by the arm 12. The arm '26 when in use engages the receiver-head 14 and the socket 28 and retains the receiver in proper position for use. This position of the receiver-head normally maintains the spring 16 under tension, and immediaiely upon the arm 26 being swung upwardly the receiverhead' and arm 12 return to their normal positions, closing the circuit between the blocks 19 and no1ifying the central operator that the telephone is out of use. Where persons cannot use their left ear for receiving a message the thumb-screw 7 can be loosened and the combined transmitter-frame 14 swung to the position illustrated in dotted lines of Fig. 1; at which time the thumb-screw may be tightened and firmly hold the frame in its reverse position.

From the foregoing description it will be obvious that I have devised a novel form of receiver-support for telephones that Will always he inposition convenient to apersons ear and can be easily moved Without the use of the .hands for placing the same in circuitwith a telephone-circuit to receive a message. The transmitter and receiver frame is preferably constructed 'of light and durablemetal and as a Whole will be made of such a size as to occupy a compara'ively small space in the compartment Where it is used.

The pivotal connection of the frame with the reversible plate allows the frarre to be adjusted at any desired inclination, this also being true of the receiver carried by the pivoted ar n of said frame. connections of the parts of my inproved receiver-support allow. the receiver and trans-. mitter to be adjusted whereby itcan be easily used. I do not care to confine myself to the manner of establishing electrical connections with the receiver and trans nitter, as my invention entirely resides in the reversible adjustable combined trans nitter and receiver franc and a suitable means for automaticallvplacing a telephone in use.

Such changes in the size, proportion. and minor details of construction as are permissile by the appended clai us may beresorterl ,to Without departing from the spirit and scope of the invention.

What I clai n, and desire to secure by Letters Patent, is

1 In a receivr'er-support for telephones,the

combination with a suitablesupport, and a trans ritter, of a reversible plate carried by said'support, an ar n carried by said plate, a frame pivotally connected to said arm and supporting said trans I ittcr, an arin pivoted in said frame, a receiver pivotally mounted upon said arn, a casing carried by said frame, contact-blocks arranged in said casing, a bridge carried by said pivoted a in and The various pivotal adapted to contact with said blocks, means to hold said bridge in cngage'rent with said blocks, contact-sir rs arranged in said casing, a stirrup carried by said pivoted arm and norm ally disengaging said contactarms,,electrical connections between said transmitter,
